ABSTRACT 3D modelling of objects is a way of obtaining information, while the visualization of geospatial data is becoming a production task in the scope of surveying. Visualization of geospatial data provides effective tools for analysis information about the land surface, land cover, its features, properties etc. Computer animations, both 2D images and 3D are becoming additional, expected and clear form for presentation results of geodetic field work. The most frequently presented part of reality in the 3D is terrain relief displayed as Digital Terrain Model – DTM. DTM is now an essential product to start many investment processes. The second most commonly mapped geographical components in 3D are buildings. Terrain modelling is becoming increasingly important, both in scientific and commercial applications. The third dimension of the map enables to recreate reality. Developing relief, buildings and other features is possible because of new technologies like LIDAR or RTK. Terrain modeling is becoming increasingly important, both in scientific and commercial applications. Using GIS tools enables to conduct studies on geomorphological aspect of landform research, creating cut-edge visualization and many more. The third dimension of the map facilitates intuitive 3D perception, interaction and collaboration with geospatial data. Observer gets an impression of viewing reality. The use of 3D technology allows for the transition from the flat paper map to the virtual map and build three-dimensional models.
